SHEET GLASS HANDLING APPARATUS
John H. Moller, Charleston, W. Va., assignor to
Libbey-Owens-Ford Glass Company, Toledo,
Ohio, a corporation of Ohio
Application February 20, 1936, Serial No. 64,823
8 Claims.
(Cl. 214—130‘)
The present invention relates to improvements
in glass handling apparatus and more particu
larly to apparatus for handling relatively large
sheets or plates of glass.
In the production of continuous sheet glass ac
cording to certain well known processes, the con
tinuous sheet or ribbon of glass, after being
formed, is carried horizontally through an anneal
ing leer and emerges therefrom onto a so-called
10 capping table upon which the said sheet or ribbon
is cut transversely into sheet sections and upon
which the opposite side edges of the individual
sheet sections may also be trimmed off if desired.
The aim of this invention is the provision of a
15 glass handling apparatus of relatively simple yet
compact and durable construction for receiving
the individual sheet sections horizontally from the
capping table, moving said sections to an upright
position, and transporting them to any desired
location in the plant for further treatment or for
packing.
Other objects and advantages of the invention
will become more apparent during the course of
the following description when taken in connec
25 tion with the accompanying drawings.
In the drawings wherein like numerals are em
ployed to designate like parts throughout the
same,
Fig. 1 is a diagrammatic plan view of glass
130 handling apparatus constructed in accordance
with the present invention and shown in position
to receive the individual sheet sections from the
capping table,
Fig. 2 is a side elevation of the glass handling
apparatus,
, Fig. 3 is an end view thereof,
Fig. 4 is a plan view of the apparatus, and
Fig. 5 is a detail section taken substantially on
line 5—5 of Fig. 4.
With reference to the drawings and particu
* 40
larly to Fig. 1, Ill designates the outlet end of a
horizontal annealing leer of any conventional
or preferred construction and II a continuous
sheet or ribbon of glass emerging therefrom‘.
445 Positioned closely adjacent the outlet end of the
leer, in a manner to receive the glass sheet therer
from and carry it forwardly, is a moving cutting
or capping table I2 which travels in the same di
rection and at the same speed as the continuous
R50 sheet II. This table may take a variety of differ
ent forms but is here shown, by way of example,
as comprising an endless belt I3 trained about
spaced rollers or drums I4 and I5 which are ro
tatably supported at their opposite ends by the
155 horizontal supporting members I6 and I1, one of
said rollers or drums being positively driven in any
preferred manner to move the endless belt in the
proper direction and at the desired speed.
As the continuous sheet or ribbon of glass II
emerges from the leer I0 upon capping table I2, 5
it is adapted to be cut transversely into individual
sheet sections of the desired length and for this
purpose there may be provided the cutting mecha
nism designated in its entirety by the numeral I8.
This cutting mechanism may be of any conven- 10
tional or approved construction since the speci?c
structural details thereof form no part of the
present invention. The cutting mechanism may,
however, be of the general type disclosed in the
patent to J. L. Drake, 1,724,261, August 13, 1929, .15
and is adapted for movement with the sheet dur
ing the transverse scoring thereof whereby to
permit accurate cuts.
'
The cutting mechanism I8 embodies generally
a pair of carriages I9 and 20 arranged at oppo- 20
site sides of the endless capping table I2 and
movable longitudinally thereof upon suitable
tracks (not shown) but which are located beneath
the upper horizontal flight of said table. Extend
ing transversely across the table and connecting 25
the carriages I9 and 20 is a supporting cross
member 2I upon which is slidably mounted a
cutter carrier 22 carrying the cutter 23. The cut
ter carrier 22 and cutter 23 are movable along the
cross member 2| by an operating rod 24, and 30
upon drawing of the said cutter across and. in con
tact with the continuous sheet II, it is adapted to
effect the transverse scoring thereof as indicated
at 25. The glass ribbon is then broken along the
score line 25 in the well known manner to pro- '35
vide individual sheet sections, one of which is
shown at 26. If desired, the opposite longitudinal
side edges of the sheet can also be trimmed off
upon the capping table I2.
Positioned at the outer end of the capping table 40'
. I2 to receive the glass sheet 26 therefrom and to
transport it to any desired location in the plant
is the improved handling apparatus provided by
‘the present invention and designated in its en
tirety by the numeral 21. This handling appa- 45
ratus includes generally a movable or portable
carriage or truck A. upon which is mounted a
tilting frame or rack B which is adapted to re
ceive the glass sheet 26 thereon while disposed
in a horizontal position as indicated by the full 50
lines in Fig. 3, after which it is swimg to an up- 7
right position as shown by the broken lines and
,while in this position is moved to any desired
location in the plant.
The carriage A consists of a substantially rec- - 55
2
2,106,573
tangular supporting frame comprising the spaced
horizontal end members 28 and 29 connected
together at one end by the horizontal side mem
ber 30 and adjacent their opposite ends by the
horizontal side member 3|. Secured to the side
member 3|, adjacent the opposite ends thereof,
are uprights 32 and 33 which are connected to
gether adjacent their upper ends by a horizontal
connecting beam ‘34;. ?ecured to the side mem
10 ber 38, adjacent the opposite ends thereof, are
uprights 35 and 36 and a plurality of intermedi
ate uprights 31 are also secured to said mem-v
ber between the ends thereof. -All of the up
rights 35, 36 and 37 are connected together ad
jacent their upper ends by a horizontal connect- _
ing beam 38.
Extending between and secured to the uprights
20
32 and 33 and the horizontal connecting beam
38 are transverse cross pieces 39 and ‘40; and the
carriage may be further strengthened by brace
boards 4| and v42 secured at one end to the cross
pieces 39 and 40 and at their opposite end to
the horizontal connecting beam 34.
The uprights 35, 36 and 31 project upwardly
beyond the ‘cross pieces 39 and 40 and passing
therethrough is a rod 43 upon which the tilt
ing frame or rack B is carried. The carriage A
is mounted upon wheels 44 arranged at the four
corners thereof and carried by the end mem
30 bers "28 and 29 whereby the said carriage can
bevfreely moved about to transport the glass to
any desired point.

The tilting frame B is substantially rectangu
lar and comprises the side members 45 and 46
and the end ‘members ‘41 and 48. Extending be
tween and carried by said side members 45 and
‘46 ‘are ‘a plurality of intermediate members 49
arranged parallel with the end members 41 and
‘48. The end members 'of the tilting frame B are
arranged outwardly of the ends of carriage A
and are pivotally mounted intermediate their
‘en's; upon the rod 43.
The end members 41 and 41B ‘and also the in
termediate members 49 of the tilting frame'are
» provided with‘aplurality of freely rotatable'roll
ers 7'59 carried ‘by brackets 5| having vertical
depending stems 52 which are loosely received
within the frame members so as to-‘permit bodily
rotary ‘movement ‘of the ‘rollers about Vertical
axes as well as permitting them to freely rotate
‘about horizontal axes.
The tilting ‘frame Bis ‘normally maintained in
‘a horizontal position, as'shown‘by‘the ‘full lines
‘in Fig. 3,‘, to receive the glass sheet thereupon
‘from the ‘capping table, ‘and after the lsheet'is
received thereon the fsaid'frame is tilted to move
the "said ‘sheet to an upright position as ‘indi
‘cated by the broken lines._ When in this posi
'60
tion, the glass sheet is supported on edge upon
casing, the forward movement of the bolt being
limited by a shoulder 62 formed thereon. When
in extended locking position, as shown in Fig. 5,
the bolt projects through an opening in the latch
plate 63 and is received within a recess 64 in 5
block 65 carried by beam 34.
The latch bolt 59 projects beyond the opposite
end of the casing 60 and has pivoted thereto as
at 66 an operating rod 61 which is provided at its
forward end with a handle portion 68. When 10
the tilting frame B is moved to horizontal posi
tion, it will be locked in such position by the
latch bolt 59. However, when it is desired to swing
the ‘frame to its upright position, it is simply
necessary‘ forthe operator to grasp handle 68
and ‘pull rod 61‘ forwardly, thereby withdrawing
15
the latch bolt 59 from looking position where
upon the ‘counterweights 54 will act to automati
callyuswing the frame upon rod 43 to upright
position.
20
The carriage A, if desired, can also be provided
at ‘each end thereof, with a conventional type of
door stop or check 69 for maintaining the car
riage in proper position during the receiving of
the glass sheet upon the tilting frame or its re 25
moval therefrom. Since these stops may be of
any Well known type readily obtainable on the
market, it is not considered necessaryto either
illustrate or describe in detail the construction
and operation thereof.
30
It is to be understood that the form of the
invention herewith shown and described is to be
taken as the preferred embodiment of the same,
and that various changes in the shape, size and
arrangement of parts may be resorted to without
‘departing from the spirit of the invention or ‘the
scope _of ‘the subjoined claims.
